Look at the Nugier site, they have pdf breakdown pics of the frame on the 40 & 50 ton presses. Built in winch & cables allowed changing table height in 30 seconds too. The entire H frame is bolted together and the main table rests on 2 pins (1" maybe?) at either side through the frame. You could take up several inches of slack, shift to low speed, and pop the bearing loose in a few seconds. When it contacts the work, twist the knob to slow speed, pull the bar out to full length and HANG on it if needed. Center the bar and it counterbalances itself so it's very fast and easy to pump in high speed. The handle was a steel bar about 4' long that slides in it's holder and it's mounted at shoulder height. I was thinking about using 10 or 12 mm bolts to join the beams.Ĭan anyone see any potential issues with my logic? (potential for bolts shearing/ beams bending etc)ĭuring many years worked in automotive machine shops, pressing axle bearings and the like, the sweetest press to use was the Nugier 40 ton, 2 speed, hand operated pump model.
i have a fair idea of how im going to weld the bolting plates onto the frame, but as to the bolt sizes im at a loss. but i would ideally like to be able to unbolt the frame for portability. Im certified in welding, so nothing scares me there. My Problem lies with the Joining of the Channel steel. I believe this will give me enough strength to cope with the forces involved and will allow me to bolt the Ram onto the top crossbar (it has been designed to do this already). I am looking to build a "H-Frame" type press out of Structural channel with dimensions 200x75mm. I have already bought the hydraulic ram and powerpack (thanks fleabay) so these is my limiting factor for the build. I am planning to build a 35ton Hydraulic press in the coming week to satisfy my desire to make damascus steel blades. Hello all out there and a special hello to any engineers (mechanical/structural) as well
